It can easily be understood that the news of the engagement caused the most intense excitement throughout this country, and indeed throughout the whole world. In the South, all was rejoicing over this signal success of the Confederate ship. Bells were rung, and jubilees held, in all the Southern cities. An officer of the "Merrimac," who was despatched post-haste to Richmond with reports of the engagement, was met at every station by excited crowds, who demanded that he tell the story of the fight over and over again. At last the starving people of the Confederacy saw the way clear for the sweeping away of the remorseless blockade.

In the North, the excitement was that of fear. The people of seaboard cities imagined every moment the irresistible iron ship steaming into their harbors, and mowing down their buildings with her terrible shells. The Secretary of War said, at a hastily called cabinet meeting in Washington: "The 'Merrimac' will change the whole character of the war: she will destroy every naval vessel; she will lay all the seaboard cities under contribution. Not unlikely we may have a shell or cannon-ball from one of her guns, in the White House, before we leave this room."

In this excited state, wild with joy, or harassed with fear, the whole country went to sleep that March night, little dreaming that the morrow would change the whole face of the naval situation, and that even then a little untried vessel was steaming, unheralded, toward Hampton Roads, there to meet the dreaded "Merrimac," and save the remnants of the Federal fleet. Then no one knew of the "Monitor;" but twenty-four hours later her name, and that of her inventor Ericsson, were household words in all the States of the Union and the Confederacy.

"Merrimac" and "Cumberland."

Capt. John Ericsson was a Swedish engineer, residing in this country, who had won a name for himself by inventing the screw-propeller as a means of propulsion for steamships. He and a Connecticut capitalist, C. S. Bushnell by name, had ever since the opening of the war been trying to induce the Government to build some iron-clads after a pattern designed by Ericsson, and which afterwards became known as the "monitor" pattern. Their labors at Washington met with little success. After a long explanation of the plan before the wise authorities of the Naval Board, Capt. Ericsson was calmly dismissed with the remark, "It resembles nothing in the heavens above, or the earth beneath, or the waters under the earth. You can take it home, and worship it without violating any Commandment." Finally, however, leave was obtained to build a monitor for the Government, provided the builders would take all financial risks in case it proved a failure. So, with this grudging permission, the work of building the warship that was destined to save the Federal navy was begun. Work was prosecuted night and day, and in one hundred days the vessel was ready for launching. Great was the discussion over her. Distinguished engineers predicted that she would never float; and many attended the launch expecting to see the vessel plunge from the ways to the bottom of the river, like a turtle from a log. So general was this opinion, that boats were in readiness to rescue her passengers if she went down. But Capt. Ericsson's plans were well laid. The great vessel glided with a graceful dip into the river, and floated at her cables buoyantly. She was a strange-looking craft. All that was to be seen of her above water was a low deck about a foot above the water, bearing in the centre a large round iron turret pierced with two great portholes. Besides the turret, the smooth surface of the deck was broken by two other elevations,—a small iron pilot-house forward, made of iron plates about ten inches thick, and with iron gratings in front; aft of the turret was a low smokestack. Beneath the water-line this vessel had some strange features. The upper part of her hull, forming the deck, projected beyond her hull proper about four feet on every side. This projection was known as the "overhang," and was designed as a protection against rams. It was made of white oak and iron, and was impenetrable by any cannon of that day; although now, when steel rifled cannon are built that will send a ball through twenty inches of wrought iron, the original "Monitor" would be a very weak vessel.

The turret in this little vessel, which held the two guns that she mounted, was so arranged as to revolve on a central pivot, thus enabling the gunners to keep their guns continually pointed at the enemy, whatever might be the position of the vessel. When the time for the first battle actually arrived, it was found that the turret would not revolve properly; but in later ships of the same class this trouble was avoided.

It was at two o'clock on the morning after the day on which the "Merrimac" had wrought such havoc among the ships of the North, that this queer-looking little vessel steamed into Hampton Roads. As the gray dawn began to break, she passed under the quarter of the "Minnesota," and cast anchor. The tars on the great frigate looked curiously at the strange craft, and wondered if that insignificant "cheese-box on a raft" was going to do battle with the dreaded "Merrimac." Small hopes had they that their noble frigate would be saved by any such pygmy warship.

In the mean time, the men of the "Merrimac" up at Norfolk were working energetically to prepare her for the destruction of the rest of the Union ships. Her ram was tightened in its place, her steering apparatus overhauled, and some changes made, and her rickety engine was patched up. At daybreak all was bustle as the ram prepared to move down on the Union fleet. But just as she was about to start, her officers saw the queer craft lying by the "Minnesota," which they at once knew to be the Ericsson "Monitor." Her appearance was not very terrible; but, nevertheless, the Confederates felt that she had appeared at a most inopportune moment for them. Still they raised anchor, and started down the bay to meet their mysterious enemy.
